Six green DDR5 server memory modules with black heat spreaders and gold contacts

NEMIX RAM

NEMIX RAM 288GB (6 x 48GB) DDR5 6400MHz PC5-51200 2Rx8 1.1V ECC RDIMM Server Memory Kit

SKU CH-DQ50-PPGQW

A 288 GB kit of six 48 GB DDR5-6400 ECC registered DIMMs running at 1.1 V with CL52 latency for server workloads

  • Rated speedDDR5 6400 (PC5 51200)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latency52
  • Rated voltage1.1 V
  • Buffer typeRegistered
  • Memory rank2Rx8
  • 288GB total capacity from six 48GB modules
  • DDR5 6400MHz speed delivers PC5-51200 bandwidth
  • ECC registered design protects data integrity
  • Dual-rank 2Rx8 organisation increases memory density
  • Low 1.1V operation reduces power consumption

Capacity and configuration

This kit provides 288 GB of DDR5 server memory across six 48 GB registered DIMMs. It is built for enterprise platforms that require ECC protection and registered signalling.

Upgrade path and fit

The modules replace lower-capacity DDR5 RDIMMs or fill empty slots in compatible server boards. The jump is worthwhile when workloads exceed the addressable memory of smaller kits and the platform supports 6400 MT/s operation.

Sustained-load behaviour

Registered buffering and on-die ECC maintain data integrity during continuous operation. The 1.1 V operating voltage helps limit thermal output while the 2Rx8 organisation keeps latency stable at CAS 52.

Questions about this item

Will the 288-pin DDR5 RDIMM modules fit my server’s memory slots?

Yes, each 48 GB module uses the standard 288-pin DDR5 RDIMM form factor for server DIMM sockets.

Do I need to populate all six slots at once, or can I install the 2Rx8 modules individually?

Install each 48 GB 2Rx8 module one at a time, seating it fully until the retention clips click; mixing ranks or leaving gaps can prevent the server from posting.

When should I expect to replace these ECC RDIMMs under normal server workloads?

ECC RDIMMs have no scheduled replacement interval; swap a module only if the system logs correctable errors or a DIMM fails diagnostics.
